you can make it work the dude above had some good advice i also heard that it has nutrient lock up problems when using other nutes. ive never used it except for houseplants so i cant give the best info. most people on this site will tell you to stray away from it though
 
I used all types of mg soil from home depot.It will grow your plants yeah but better soil would be better.Try adding some more perlite and it should be fine..

I would not buy a solid brick of gold for a quarter which had the word Miracle Grow stamped on the surface. And thats final:)

you can always take it and do a good flush before you use it, if you have some florakleen or clearex or any salt leaching shit around that would be good also, try and wash as much of the mg shit out as possible, check my threads...i just finished my own nutrient challenge and you will see what mg does to plants

I would be very careful about flushing as it has time release ferts in it that are activated by water. if you do flush, keep flushing for several days to be sure you flushed all the ferts out.
like suggested above, it can be used but be careful about overwatering. can you mix it w/ other soil?

all i can say is, from first starting this thread, i started like 25 plants with mircle gro with the slow release nutes in them. and my plants are looking nice. no problems whatsoever. I am watering these straight water, and they look just as big and healthy as other plants i started the same time with fox farms ocean forest soil.

Some time release fertilizers regulate the rate of break-down of their timed-release products by temperature. For instance, if the fertilizer is advertised to feed for 3 months, that's based on temperatures in the low 70's or above. At temperatures below the chosen/set degrees the fertilizer will not release regardless of how much water is run through the soil.
 
Has anyone actually researched Miracle Grows time release fertilizer to see if it is released only after a certain temperature has been reached or has gone beyond it and the plant is then watered or if it is strictly a water soluble release fertilizer?
 
Even if it is strictly water soluble if someone puts out the effort they can pour gallons of water through a pot in a day and that is far more than the plant could ever begin to use so far more unwanted fertilizer would be flushed than taken up by the plant.
 
If the option is leave it and possibly kill the plant slowly or flush the heck out of it in one day I guess everyone has to decide which is the least risky option.
 
One option that will work, as long as the plants are not in flower so you do not want to do much to them that could stress them in any way, is to do a bare root transplant and get rid of the soil with time release fertilizer in it and replace it with non-fertilized soil. It is simple and it is safe and the plant will not take in the unwanted fertilizer in the process.
